3. Настройка
- Распакаванне: Асцярожна выміце ўсе кампаненты з упакоўкі. Захоўвайце арыгінальную ўпакоўку для наступнай транспарціроўкі або захоўвання.
- Размяшчэнне: Размясціце мікраскоп на ўстойлівай роўнай паверхні, удалечыні ад прамых сонечных прамянёў, высокіх тэмператур, пылу і вібрацый.
- Падключэнне сілкавання: Connect the power cord to the microscope's power input (AC100V-240V, 50/60Hz) located at the rear of the base, then plug it into a suitable electrical outlet. Ensure the power switch is in the OFF position before connecting.
- Усталёўка акуляра: Insert the desired eyepieces (e.g., WF10x) into the eyepiece tubes of the binocular head.
- Binocular Head Adjustment: If the binocular head is rotatable, adjust it to a comfortable viewпазіцыя.

4. Інструкцыя па эксплуатацыі
- Уключэнне: Flip the power switch located on the rear of the microscope base to the ON position. Adjust the illumination intensity using the dimmer control.
- Размяшчэнне ўзору: Place a prepared microscope slide onto the mechanical stage. Secure it with the stage clips. Use the stage control knobs to center the specimen area of interest over the condenser aperture.
- Magnification Selection: Rotate the revolving nosepiece to select the lowest power objective lens (e.g., 4x). Ensure the objective clicks firmly into place.
- Факусоўка:
- While looking through the eyepieces, use the ручка грубай факусоўкі каб прыблізна сфакусаваць узор.
- Затым выкарыстоўвайце ручка тонкай факусоўкі for precise focusing until the image is sharp and clear.
- Рэгуляванне асветленасці:
- Adjust the brightness using the dimmer control.
- Adjust the iris diaphragm lever on the condenser to control the amount of light reaching the specimen and improve contrast.
- Рэгуляванне міжзрэнкавай адлегласці: Adjust the distance between the two eyepiece tubes by gently pushing them together or pulling them apart until you see a single, circular field of view.
- Рэгуляванне дыёптрый: If one eyepiece has a diopter adjustment ring, focus on the specimen with your dominant eye (usually the right eye) using only the fine focus knob. Then, close your dominant eye and use the diopter adjustment ring on the other eyepiece to focus for your non-dominant eye without touching the fine focus knob.
- Higher Magnification: Once focused at low power, rotate the nosepiece to a higher power objective. Only minor adjustments with the fine focus knob should be needed due to the parfocal design.
- Immersion Oil (for 100x objective): For the 100x objective lens, a drop of immersion oil must be placed directly on the specimen slide. Lower the objective into the oil carefully. After use, clean the 100x objective and slide thoroughly with lens cleaning solution.

5. Тэхнічнае абслугоўванне
- Чыстка лінзаў: Use a soft, lint-free lens cleaning cloth and a specialized lens cleaning solution. Never touch optical surfaces with your fingers.
- Генеральная ўборка: Працярыце корпус мікраскопа мяккай тканінайamp тканіна. Пазбягайце выкарыстання абразіўных ачышчальнікаў або растваральнікаў.
- захоўванне: When not in use, cover the microscope with a dust cover to protect it from dust and debris. Store in a dry, cool place.
- Замена засцерагальніка: If the illumination fails, check the fuse located near the power input. Replace it with a fuse of the same type and rating (a spare fuse is included).
6. Выпраўленне непаладак
| праблема | Магчымая прычына | Рашэнне |
|---|---|---|
| Няма асвятлення | Power cord disconnected, power switch off, dimmer at minimum, blown fuse. | Check power connection, turn on switch, increase dimmer, replace fuse. |
| Image unclear/blurry | Incorrect focus, objective lens dirty, eyepiece dirty, slide upside down. | Adjust focus, clean lenses, check slide orientation. |
| Цёмнае поле view | Iris diaphragm closed, low illumination, objective not clicked into place. | Open diaphragm, increase brightness, rotate nosepiece until objective clicks. |
| Two overlapping images | Interpupillary distance incorrect. | Adjust interpupillary distance until a single field of view is seen. |
